The purpose of waterproofing structures is the protection of existing and new buildings against the ingress of moisture respectively of all forms of water (residential houses, tunnels, fundaments, etc.) as well as against the leakage/outflow of water or other (environmentally hazardous) liquids (swimming pools, retention basins, tanks, etc.). The determination of the adequate, preventive and/or additional sealing measures (bituminous sheeting, foil, coating,
Joint tape,
injection hose,
injection hose and
curtain injection, etc.) requires detailed knowledge of the object (existing, new, historical building, etc.) as well as of the conditions as e.g. the load cases (
Capillary water absorption, pressing/non-pressing water, rainwater, etc.); cellar, façade, roof, utilisation class (residential building, parking deck, etc.). For structures protecting against leakage/outflow the hazard class of the liquid (water, oil, caustic, radioactive, etc.) already determines the type of construction (wall/base, tank, etc.), the selection of the building material (special concretes, etc.) as well as the further sealing measures and materials.
